What is the problem with complete automatic inference?
Wouldn't it be possible to deduce the flags in the bottom up 
direction of a function call hierarchy?
I guess it is possible for the compiler to see the right choice 
of flags for a function, which doesn't call other functions. E.g. 
make it @safe if possible, @nogc if possible and so on.
Then it should process function after function until all 
functions are done.
